TISS76-2 hour rule

 Legacy as of January 1, 2013

Special instruction regarding collection of TISS76 apply for two hours on either side of midnight.

1. If a patient is admitted to ICU at or after 2200, nursing activities for the time before midnight are included on the next day's TISS score.
2. If a patient passed away or is discharged from ICU at or before 0200 hours, nursing activities for the time after midnight are included on the previous day's TISS score.
3. If a patient's time of admission and discharge falls within the above 2 periods, i.e. LOS ≤ 4 hours, one TISS score must be done using the admit date.

Examples

• If a patient is admitted at 2200 hours on November 2.01 then the Day 1 TISS will start on November 3.01 and will be done done retrospectively by the night staff on November 3.01 looking back at the previous 26 hrs of care.

• If a patient is discharged at 0200 hours on December 10.01 then the last day TISS score will be on December 09.01 which will be 26 hours long to include these 2 hours.

• IF ADMITTED between 2200 & 2400hr is Y then the first DATE should be Admit Date + 1 .
  • Example. Admit date=May1 then first DATE = 2

Legacy SAS Programming checks

• IF DISCHARGED between 0001 & 0200hr is Y then the last DATE should be Discharged Date - 1.
  • Example. Disch Date=May8 then last DATE = 7

• IF both 'ADMITTED between' and 'DISCHARGED between' are and
  1. LOS < 1day, then fill up only one DATE
     • Example. Admit=May1 Disch=May2 then first DATE=either 1 or 2 whichever has the longer time (#col= 1 )
  2. LOS >1day then fill up the first DATE as Admit date+1 and the last DATE as Discharged Date - 1
     • Example1. Admit=May1 Disch=May3 then first DATE=2 (# col=1)
     • Example2. Admit=May1 Disch=May4 then first DATE=2, last DATE=3 (# cols=2)

• If both not 'ADMITTED between' and 'DISCHARGED between', then the first DATE should be the Admit Date and the last DATE should be the Discharge Date
  • Example1. Admit=May1 Disch=May2 then first DATE=1, last DATE=2 (# cols=2)
  • Example2. Admit=May1 Disch=May3 then first DATE=1, last DATE=3 (# cols=3)
